ADJUSTABLE DOUBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 385,29L, dated June 26, 1888;

Application filed March 20, 1888. Serial No. 267,810. (No model.)

To all whom it may concern.-

Be it known that I, Asa A. BILLINGSLEA, a citizen of the United States, residing at Cherry 7 G-rove,in the county ofGrant and State ofAr- 5 kansas, haveinvented certain new and useful Improvements in an Adjustable Double Plow; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it re appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to single and double plows; and it consists in the novel construction and arrangement of its several parts, hereinafter described.

In the accompanying drawings, Figure 1 is 2c a top plan view of my invention, the parts shown by Figs. 3 and 4 being left off. Fig. 2

is a side elevation of my invention having the parts shown by Figs. 3 and 4, the cross-beams,

side beams, feet, and lock bar being left off. 2 Figs. 8, 4, 5, 6, 7, 8, 9, 10,11, and 12 are detail views.

My invention is described as follows:

In the accompanying drawings, A represents the tongue-beam.

B represents the cross swinging beam.

represents the side bars, which are bolted to the outer ends ofsaid crossbeams-one on the upper and one on the under side of the same. Said crossbeams B are pivoted at their center against the under side of the tongue-beam A. In the center of the side bar, 0, are recesses c, to receive thenpper ends of the plowstandards 1). (Shown in Figs. 5, 6, and 7.) To the right-hand end of the rear erossbeam B is pivoted a lock-bar, E, having in it looknotches c. Said lockbar slides in between the front cross-beam B and the tongue-beam A, its notches fitting over the center bolt, 6.

By the above-described construction I am. 4 5 enabled to set my plow-points one immediately opposite the other and on a line of right angles with the said tongue-beam A; orI may advance the right point and retard the left, or advance the left and retard the right, and in whatever position I may place them I can securely lock them by lock bar E, and in whatever position I place them the plowpoints stand directly to the front and cut fun rows exactly parallel.

The plow-standards D consist of a solid foot or landside, d, from which extend upward two flat arms, at, which are perforated at their up per ends and adapted to fit in the recesses c in the side bars, 0, and to be bolted thereto, the bolt passing through one of the said perforations in said standards and between "the upper and lower side bars, 0. This arrangement holds the said standards perfectly secure in place in said recesses and enables me to make the standards longer or shorter, or, in other words, set the wood-work higher or lower from the ground, to adapt the plow to tall or short persons. At the rear of said plow, and be tween the rear end of the tongue-beam A and the rear cross -beam B, is placed a slotted wedge, F, the rear bolt, f, passing through the said beams and the slot f in said wedge. The said wedge F is of considerable thickness at its rear end and tapers down to a line edge at the front end. The office of this wedge is to regulate the depths of the plow points. \Vhen I wish the plow-points to run deep into the ground, I draw the said wedge back as far as the boltf will allow it to come, and I lessen the depth of the cut by driving said wedge in more and more, as I wish the more and more to lessen the depth. When said wedge is made of wood, I place along on its under face small teeth f but when cast its lowcrfacc has corrugationsf.

In the model from which the present drawings are made I use half-shovel mold-board points G, which are secured to the plowstandards D by a single bolt passing through said plow-points and the slot left between the arms (1. The upper end of said plow-point is cut perfectly square across, about one half its width, that it may firmly abut against the abutment H, the lower end of which is out perfectly square across. Said abutment H is secured to the front face of the said standard by a bolt, h, passing through the same and between the said arms 01, secured by a nut, h, and prevents the said plowpoint from slipping up, and, impinging against said plow-point, prevents it from turning to the right or left. Said abutment H is sometimes provided with a wing or mold-board, h in which case I can use a much smaller point than the one represented by G, slipping the said abutment H lower down, in which case the wing or moldboard h performs the office of the wing or mold-board g on the point G.

When Iuse two or more horses to my plow and wish to out very deep furrows and turn a very heavy mold, I use both the plow-point G, having the mold-board g, aud the abutment H, having the mold-board if, the said mold-boards substantially forming one large mold-board.

When I wish to change my adjustable double plow into a single plow, I unscrew the nuts from the bolts 0 andf and take off from the tongue-beam A the crossbeams B, side bars, G, and wedge F, and put onto said tonguebeam A the standard J, as shown in Fig. 4, securing the same in place by a collar, 9', and two bolts and nuts one passing through the upper perforations and resting tightly against the upper face of the tongue-beam A, and the other passing through the lower perforations and resting against the under face of the same; and, when desired, I also attach to said beam inthe same manner a colter, K, Fig. 3, having the perforated arms k; When I desire to do so, I use the said standard J at the same time that I use the standards D, thus cuttingthree furrows instead of two, in which case, however, I usually use small shovel plow-points and abutment H without the mold-board h I do not confine myself, however, to anypan ticular plow points, my plow-standards D and J, in connection with the abutment H, being adapted to secure and carry any ordinary plowpoints now in use; and in addition to the three standards I may and sometimes do also 40 attach to the tongue-beam A, in front of the cross'beam B,thc coltcr K,iu the manner above described.

Having described my invention,whatIclaim as new, and desire to secu re by Letters Patent, 1s

1. In a double adjustable plow, as above described, the combination, with the tonguebeam A, cross-beam B, and lock-bar E, of the side bars, 0, having the recesses c, the plowstandards D, having the solid foot or landside (Land perforated arms d, all substantially as shown and described, and for the purposes set forth.

2. The combination, in a plow, as above described, of the recessed plates 0, slotted plowstandard D, secured to said plates, abutment H, having the mold-board h", secured to the front edge of said plow-standard, and plowpoint G, having the mold-board g, co-operating with said mold'board If, substantially as shown and described.

3. The combination, in a plow, as above de ASA A. BILLINGSLEA.
